PURPOSE:An aerosol agent that is obtained by using a concentrate containing pest-controlling components, inflammable components as a combustible solvent for the active ingredients and a specific amount of trichlorotrifluoroethance, thus being effective for pest control with high safety in storage and handling. CONSTITUTION:A non-inflammable mixed concentrate, which is prepared by adding 5-20wt% of trichlorofluoroethance to an inflammable mixture of pest- controlling substances such as exmin. neopynamin or fenitrothion and an inflammable seolvent such as kerosene, is, when necessary, combined with an intensifier such as piperonyl butoxide, synepirin 500, then placed in an aerosol vessel. Further, a spraying agent such as a liquefied gas, dimethyl ether, flon, N2, dinitrogen oxide or pressurized gas is pressed into the vessel so that the pressure for the propellant reaches 1.0-7.4kg/cm<2> at 20 deg.C to give the objective aerosol. EFFECT: The aersol can continue high controlling power.
